Open Reduction using Lateral Approach in Displaced Intra-articular Fracture of Calcaneus
Kyung Jin Song, Keun Ho Yang, Joo Hong Lee
J Korean Soc Fract 2002;15(4):446-454.   Published online October 31, 2002
DOI: https://doi.org/10.12671/jksf.2002.15.4.446
AbstractAbstract PDF
PURPOSE
This study was designed to investigate the usefulness of lateral approach for accurate reduction and rigid internal fixation in comminuted intra-articular fractures of calcaneus.
MATERIALS AND METHOD
Twenty patients(21 cases) who had intra-articular fracture of calcaneus and underwent an open reduction and internal fixation using lateral approach were enrolled. Using Essex-Lopresti classification, all cases were intra-articular fracture, which joint depression type was 17 cases and 4 of severe comminuted tongue type. We compared the preoperative and postoperative change of B o h l e r 's angle and clinical results were analyzed using Paley and Halls evaluation protocol and scoring system.
RESULTS
The average B ohler 's angle was restored from 2.8 to 25.1 after operations and clinical results classified 4 well, 12 good, 4 fair, 1 poor cases. Postoperative complications were 2 cases of wound dehiscence, 1 of infection and one had sural nerve injury. Late complications included 3 cases of limitation of motion of ankle that disturb usual activity, 3 of sustained pain and 2 of traumatic arthritis and 2 cases had 2 complications at the same patients.
CONCLUSION
The lateral approach is valuable for the comminuted intra-articular fractures of calcaneus that enables accurate anatomical reduction and rigid internal fixation by providing direct exposure of subtalar joint, and also with little morbidity of neurovascular injury.

The results of Operative Treatment in the Proximal Tibial Plateau Fracture
Kyung Jin Song, Keun Ho Yang, Joo Hong Lee
J Korean Soc Fract 2002;15(4):489-496.   Published online October 31, 2002
DOI: https://doi.org/10.12671/jksf.2002.15.4.489
AbstractAbstract PDF
INTRODUCTION: The purpose of this study was to analyze the results, prognosis and complications in the treatment of proximal tibia plateau fractures, and to suggest the guideline for the proper management in the difficult cases of tibial plateau fractures.
MATERIALS AND METHODS
We have analyzed 27 cases, which surgically treated during recent five years with average 36.6 months follow-up. Patients ranged in age from 24 to 83 years at the time of hospitalization, consisting of 19 males(70.4%) and 8 females(29.6%). The type of fracture by Schatzker classification revealed in type I 3 cases(11.1%), type II 1 case(3.7%), type III 0 case(0%), type IV 3 cases(11.1%), type V 1 case(3.7%) and type VI 19 cases(70.4%). The associated injury occurred in 22 cases(81.5%), most of them were ipsilateral fibular, ipsilateral femoral and radioulnar fractures. The results were evaluated by Blokker 's criteria.
RESULTS
Screw fixation was done in 4 cases(18%) and plate fixation in 23 cases(85.2%), and bone grafting was done in 10 cases(37.0%). There were 10 postoperative complications with 3 cases of knee ankyosis, 3 cases of angular deformity, 3 cases of infection, and 1 case of traumatic arthritis. According to Blokker 's criteria, 22 cases(81.5%) had satisfactory results.
CONCLUSIONS
Accurate anatomical reduction and rigid internal fixation of the proximal tibial plateau fracture enabled early motion and normalization of injured soft tissues, and also provided functional improvement of the knee.

Treatment of Infected Nonunion of the Tibia by Ilizarov External Fixator
Jung Ryul Kim, Keun Ho Yang, Byung Yun Hwang
J Korean Soc Fract 2000;13(4):921-927.   Published online October 31, 2000
DOI: https://doi.org/10.12671/jksf.2000.13.4.921
AbstractAbstract PDF
PURPOSE
To analyze the clinical results and complications of the Ilizarov technique in the treatment of the tibial nonunion.
MATERIALS AND METHODS
Twenty-seven patients who had infected nonunion of the tibia were managed with Ilizarov external fixator form January 1992 to January 1997. Types of nonunion were classified according to Paley and status of infection were divided into AO classification. We evaluated clinical outcomes and complications which were assessed with rating system of Paley.
RESULTS
All cases obtained bony union. The mean time to union was 11.5 months. On average, healing index was 51.4 days/cm(range 28-72 days/cm) and percentage of increment was 18.5 %(range, 13-31.5 %). According to Paley criteria, bone results were good to excellent in 22 cases(81.5 %), and functional results were good to excellent in 24 cases(88.9 %). Total thirty five complications were occurred, which were classified by Paley criteria, problems in 15 cases, obstacles in 17 cases, and complication in 3 case.
CONCLUSION
Ilizarov technique is a useful method in management of the tibial nonunion, but we have to consider the complications and endeavor to reduce them.

Surgical Treatment of the Bimalleolar Ankle Fractures
Kyung Jin Song, Keun Ho Yang, Kyung Rae Lee, Ju Hong Lee, Byung Yun Hwang
J Korean Soc Fract 1999;12(4):956-960.   Published online October 31, 1999
DOI: https://doi.org/10.12671/jksf.1999.12.4.956
AbstractAbstract PDF
We designed this study to evaluate the functional outcome and to suggest the guidelines in the treatment of bilnalleolar ankle fractures with clinical and radiological analysis after operative treatment. We analyzed 35 patients with bimalleolar fractures among 90 ankle fractures and followed up for more than 1 year. All 36 fractures were classified according to Lauge-Hansen system and the Meyer criteria was used for the clinical and radiological assessment. Seventeen cases(47%) were supination-external rotation(47%), 9 cases(21%) were supination- adduction: 6 cases(17%) were pronation-abduction and 4 cases(11%) were pronation-external rotation type. Satisfactory results was obtained in 32 cases(89%) according to the criteria of Meyer in the viewpoint of clinical and radiological analysis. Satisfactory results could be obtained with early anatomical reduction and rigid internal fixation for the treatment of bimalleolar ankle fractures. Distal tibiofibular syndesmosis disruption could be spontaneously reduced without trans-syndesmotic screw fixation by early open reduction and rigid internal fixation for the bimalleolar ankle fractures. Early and more accurate anatomical reduction can reduce the post-traumatic arthritis in cases with moderate talar displacement and open fractures.
